To get the full effects of DMT it’s best to have it in a powder form (I think) then take a hit from a crack pipe. When I had a functional vape cartridge I had to take 3-5 pulls in rapid succession to get close to the same effects. That’s the point where you start seeing geometric shapes and maybe an extra dimensional being. The one I met the one time I hit from a pipe suggested I lay off the chocolate milk.

Like you suggested, I don’t think it’s very recreational, but it is a very interesting substance.
